Questions about solar in Rhode Island
How does Rhode Island pay for solar power I send to the grid?
Rhode Island is counted here as full retail net metering: each kWh you export earns the same as a kWh you would buy. We have not checked Rhode Island's rules against its utility commission yet, and some utilities pay less, so check your utility's net metering tariff.
How much did the end of the federal tax credit change payback in Rhode Island?
With the 30% credit that ended in 2025, the same system would have paid back in about 6.7 years instead of 9.6. The credit ended for systems installed after December 31, 2025. Leased systems and power purchase agreements can still pass on a business credit, but then you do not own the panels.
Is 1,294 kWh per kW a lot?
The range across states runs from about 922 kWh in Alaska to about 1,779 in the Southwest. Sunshine matters less than people expect: the electricity rate and how your utility credits exports move payback more.
